A new study suggests the craters were dug out by rocky debris after the lunar surface was struck around 3.8 billion years ago. Find out more here.

Two Grand Canyon-size features on the far side of the moon were likely formed in about 10 minutes after an unknown object slammed into the moon 3.8 billion years ago.

Two canyons that splay out from a vast asteroid crater on the moon may have been quickly formed by chains of impacts that followed the initial one

The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power of the Colorado River. Close to the moon's south pole are two canyons each comparable in size to the Grand Canyon that were born in a much different process.

Scientists proposed an explanation for the formation of Vallis Schrödinger and Vallis Planck near the lunar south pole, which are each about the size of Earth’s Grand Canyon.

The Earth's Grand Canyon took millions of years to carve, but the moon's grand canyons took about ten minutes.

The vast valleys of Vallis Schrödinger and Vallis Planck demonstrate the incredible forces that shaped the face of the Moon.

New research shows that when an asteroid slammed into the moon billions of years ago, it carved out a pair of grand canyons on the far side
